DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work suction device for sucking a work.

[0002]

2. Description of the Related Art Conventionally, as a work suction device, a vertically movable work carrier extending in the left-right direction is provided. A plurality of guide receivers are provided at appropriate intervals in the longitudinal direction (left-right direction) of the work carrier. Each guide receiver is provided with a guide extending vertically. In addition, a magnet for attracting the work is provided at the tip of each guide. A spring that constantly urges the guide receiver upward is interposed between the guide receiver and the magnet. Each guide receiver is provided integrally with the work carrier.

[0003]

By the way, since each guide receiver is provided integrally with the work carrier, when each magnet has no flexibility and the work is warped,
There is a problem that the work cannot be attracted by the magnet because the magnet surface is not horizontal with the work.

In addition, since the guide receiver moves only a predetermined length in the vertical direction, when the work is lifted, there is a problem that the magnet in a portion where the work is warped is detached from the work.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a plurality of guide receivers provided on a vertically movable work carrier to vertically support a guide having a magnet at a lower end. In the work suction device, a spring is interposed between the guide receiver and the lower part of the guide, the guide receiver includes a cylindrical guide portion for guiding the guide up and down, and The structure has a holding portion for holding from above and below, and is formed by an elastic member.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings.

Referring to FIG. 2, the work suction device 1 has a work carrier 3 extending in the left-right direction which can move up and down, and the work carrier 3 is extended in the longitudinal direction (left-right direction).
A plurality of guide receivers 5 are mounted at appropriate intervals via mounting brackets 7. A guide 9 extending in the vertical direction is attached to each guide receiver 5, and a magnet 11 is provided at the tip (lower end) of the guide 9. The guide 9 between the magnet 11 and the guide receiver 5 is provided with, for example, a spring 13 as urging means for constantly urging the guide 9 upward.

As shown in FIG. 1, the guide receiver 5 is provided on a mounting bracket 7 mounted on the work carrier 3. The guide receiver 5 is formed of, for example, rubber 15 as a hollow elastic member. The guide 9 is mounted on the axis of the rubber 15, and the upper end of the guide 9 positions the upper limit position of the guide receiver 5. A screw 17 is provided as a stopper.

More specifically, as is apparent from FIG.
The guide receiver 5 has a cylindrical guide portion for guiding the guide 9 up and down, and a holding portion for holding a mounting bracket as a part of the work carrier 3 from above and below. It is.

With the above configuration, when the work carrier 3 is lowered in a case where the work W is warped as shown in FIG.
1 descends, and the left and right magnets 11 in FIG. Further, when operated to lower the work carrier 3, the middle of the magnet 11 adsorbs the warp portion W _A of the workpiece W. Then, when lifted, the heights of the plurality of magnets 11 become constant.

As described above, the force received by the magnet 11 is received by the guide receiver 5 made of the hollow rubber 15, and the guide receiver 5 has a degree of freedom in the vertical and horizontal directions. Thus, the magnet 11 can follow the warp of the work W, and the work W can be surely attracted. Also, by relaxing the impact when the work carrier 3 stops moving up and down, the work W can be reliably lifted by preventing the work from dropping.

The present invention is not limited to the above-described embodiment, but can be embodied in other modes by making appropriate changes.

[0013]

As can be understood from the above description of the embodiment, in short, the present invention is characterized in that a plurality of guide supports (5) provided on a vertically movable work carrier (3) are provided with a magnet ( In a work suction device, a guide (9) provided with 11) is provided so as to be vertically movable and a spring (13) is interposed between the guide receiver (5) and the lower part of the guide (9). The guide receiver (5)
The work carrier (3) is provided with a cylindrical guide portion for vertically guiding the guide (9) and a holding portion for holding the work carrier (3) from above and below, and is formed of an elastic member.

As is apparent from the above configuration, in the present invention, the guide receiver 5 has a cylindrical guide portion for vertically guiding the guide 9 having the magnet 11 at the lower end, and the work carrier 3. Since the guide member 5 is deformed, the guide 9 can be allowed to incline and the work 9 can be slightly inclined. Even if there is, it can respond.

Further, since the guide receiver 5 is formed of an elastic member, the work carrier 3 is lowered, the work is held by the magnet 11 provided on each guide 9, and then the work carrier 3 is raised. This can alleviate the impact at the time of contact with the upper end of each of the guides 9 and can prevent the workpiece from falling due to the impact caused by the sudden rise of the work carrier 3.
